RFR: 8175567: Build of hotspot for arm-vfp-sflt fails

[Bob Vandette]

BUG:

https://bugs.openjdk.java.net/browse/JDK-8175567

DESCRIPTION:

The changes that were done under  (JDK-8160245 Clean up platform #defines in c1_LIR.hpp),
broke the arm-vfp-sflt build. 

Here’s a link to that original bug:

     https://bugs.openjdk.java.net/browse/JDK-8160245

This change below corrects the issue.
